Battery Case And Secondary Battery

Abstract: The present invention relates to a battery case and a secondary battery and, more specifically, to a battery case and a secondary battery which comprise: a battery case; and a gas adsorption unit accommodated inside the case, wherein a gas adsorption pack is opened when the internal temperature of the case increases. According to the present invention, gas, which is generated inside the battery due to abnormal operation or deterioration of battery life, is rapidly adsorbed by opening the gas adsorption pack filled with a gas adsorbent contained inside the case, without an additional system or sensing device, and there is an effect of providing the battery case and the secondary battery that secure the stability of the battery, prevent deformation of the battery case, lower the resistance of the battery, and also drive the secondary battery even after the gas adsorption pack is opened.
